Answer:

For both charts:

Top boxes: -12

Middle Boxes: -9

Bottom Boxes: -6

The equation is given by A = 3 ( x - 5 ) and B = 3x - 15 and they are equivalent

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

A = 3 ( x - 5 )  be equation (1)

Now , let the second equation be represented as B

Now , the value of B is

B = 3x - 15   be equation (2)

Now , on simplifying the equation (1) , we get

Substituting the value of x = 1 , 2 , 3 in equation (1) , we get

when x = 1

A = 3 ( 1 - 5 )

A = 3 ( -4 ) = -12

when x = 2

A = 3 ( 2 - 5 )

A = 3 ( -3 ) = -9

when x = 3

A = 3 ( 3 - 5 )

A = 3 ( -2 ) = -6

Now , on simplifying the equation (1) , we get

Substituting the value of x = 1 , 2 , 3 in equation (1) , we get

when x = 1

A = 3 ( 1 ) - 15

A = 3 - 15 = -12

when x = 2

A = 3 ( 2 ) - 15

A = 6 - 15 = -9

when x = 3

A = 3 ( 3 ) - 15  

A = 9 - 15 = -6

So , the values of the expressions are the same

Now , applying the distributive property on equation (1) , we get

A = 3 ( x - 5 )

A = 3x - 3 ( 5 )

A = 3x - 15 = B

Hence , the equations are equivalent

Answer:

Tan N = 4 / 3

Tan L = 3 / 4

Step-by-step explanation:

By Pythagoras theorem,

(LN)² = (MN)² + (LM)²

10² = 6² + (LM)²

100 = 36 + (LM)²

(LM)² = 100 - 36

(LM)² = 64

LM = 8

Tan N

= Opposite / Adjacent

= LM / MN

= 8 / 6

= 4 / 3

Tan L

= 1 / Tan N

= 1 / ( 4 / 3 )

= 3 / 4

Answer:

189.27 ft²

Step-by-step explanation:

Find the area of the rectangle, then the semi-circle, then add the sums.

1.) Rectangle ▭

║A = lw

║A = 10 ⋅ 15

║A = 150

2.) Semi-circle◗

║A = [tex]\frac{1}{2}[/tex](πr²)

║A = [tex]\frac{1}{2}[/tex](π ⋅ 5²)

║A = [tex]\frac{1}{2}[/tex](78.54)

║A = 39.27

3.) Adding sums +

║150 + 39.27 = 189.27

Step-by-step explanation:

Jogs every 4 days

Badminton every 6 days

If on a particular day, Ridzuan jogs in the

morning and plays badminton in the evening, how

many days later would he jog and play badminton

again on the same day?

Find the lowest common multiple of 4 days and 6 days

4 days = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52

6 days = 6, 12, 18, 24, 30, 36, 42, 48, 54

The lowest common multiple of 4 days and 6 days is 24 days

It would take Ridzuan 24 days before he would jog and play badminton again on the same day

Answer:

6z

Step-by-step explanation:

The perimeter of the rectangle is given by the algebraic expression: 4z + 6

The formula for the perimeter of a rectangle is expressed as:

P = 2(L + W)

Where:

W is width

L is length

We are given the following parameters as:

Length = z + 3

Width = z

Thus:

P = 2(z + z + 3)

P = 2(2z + 3)

P = 4z + 6

Answer:

I have no idea I am not sure i think 14

Step-by-step explanation:

Answer:

Step-by-step explanation:

So we know that a straight line adds up to 180 degrees.

This means that:

52+59+y = 180

y + 111 = 180

y = 69

We also know a triangle also adds up to 180 degrees.

This means that:

y+x+63 = 180

69+63+x = 180

x + 132 = 180

x = 48

Answer:

h = 24 ft

Given:

Radius of the base of the cone = 12 in.

The slant height of the cone = 15 in.

To find:

The lateral surface area of the given cone.

Solution:

The lateral surface area of the cone is:

[tex]LA=\pi rl[/tex]

Where, r is the radius of the base of the cone and h is the slant height of the cone.

Putting [tex]r=12,h=15[/tex], we get

[tex]LA=\pi (12)(15)[/tex]

[tex]LA=180\pi[/tex]

The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.

Answer:

Lateral is 180π

SURFACE AREA IS 340π

Step-by-step explanation:

The graph of g(x) is (a) an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5).

The function f(x) is given as:

[tex]f(x) = 2(0.4)^x[/tex]

[tex](x,y) \to (-x,y)[/tex]

This means that:

[tex]g(x) =f(-x)[/tex]

[tex]f(-x) = 2(0.4)^{-x}[/tex]

[tex]g(x) = 2(0.4)^{-x}[/tex]

Hence, the graph of g(x) is graph (a)
